      <p>The DB_ENV&gt;set_tas_spins and DB_ENV&gt;get_tas_spins methods have
been renamed to <a href="../api_reference/C/mutexset_tas_spins.html" class="olink">DB_ENV-&gt;mutex_set_tas_spins()</a> and
<a href="../api_reference/C/mutexset_tas_spins.html" class="olink">DB_ENV-&gt;mutex_set_tas_spins()</a> to match the new mutex support in the Berkeley DB
4.4 release.  Applications calling the old methods should be updated to
use the new method names.</p>
      <p>For backward compatibility, the string "set_tas_spins" is still supported
    in <a href="../programmer_reference/env_db_config.html" class="olink">DB_CONFIG</a> files.</p>
      <p>The --with-mutexalign="ALIGNMENT" compile-time configuration option has
been removed from Berkeley DB configuration.  Mutex alignment should now be
configured at run-time, using the <a href="../api_reference/C/mutexset_align.html" class="olink">DB_ENV-&gt;mutex_set_align()</a> method.</p>
